(1) In defense of the 701, it has good disk and video performance for a
486; my day-to-day work isn't all that much faster on my P133 machines.
(Perhaps the PC Mag bmarks had the machine in one of the power
conservation modes.)
(2) As for the projected speedup with the AMD chip, when I changed my
desktop 486DX2-66 to the AMD586-133 I expected only a marginal increase,
and was pleasantly surprised to see substantial real-world improvement
(see the doc I posted at my website, www.math.hawaii.edu/~ross/cpu).
Not quite P75, but suprisingly good. However, I personally wouldn't pay
$400 for this amount of speedup.

The AMD *does* have a write-back cache (though some system boards don't
let you enable this).
